25 Clinical Trials for Various Conditions
This is a multi-center, hospital based, cross-sectional study based on data from patient medical records, including laboratory results. The study will include adult patients with chronic (\> 1 year duration) primary Immune Thrombocytopenia (ITP) only. Patients will be identified based on a laboratory confirmed diagnosis of ITP in the medical records, where there is also a physician-confirmed diagnosis of primary ITP. If patients consent to take part in the study, a routine clinical visit will also serve as the study visit. All study participants will have a routine blood test as part of their standard clinical care at the study visit, and this same procedure will be used to collect supplementary blood samples to assess a variety of biomarkers. Data will be collected using a combination of chart review, clinical outcome assessment administration, and laboratory results through blood tests.
The purpose of this study is to describe the number of months with a platelet response over a 12 month treatment period and to describe ITP remission rates in adults with ITP receiving romiplostim.
The primary objective of this study was to assess the efficacy of 3 dose levels of lusutrombopag (0.5 mg, 0.75 mg, and 1.0 mg) and placebo on platelet count.
The purpose of this study is to determine whether Fostamatinib Disodium is safe and effective in the treatment of Adult Refractory Immune Thrombocytopenic Purpura (ITP).
The purpose of this study is to assess the ability of LGD-4665 given daily by mouth to increase platelet counts in the treatment of patients with ITP (immune thrombocytopenic purpura). LGD-4665 increased platelet counts safely and tolerably compared to placebo in healthy volunteers. This study will examine the safety, tolerability and efficacy of 7.5 mg capsules of LGD-4665 to increase platelets compared to placebo, randomized 2:1, during blinded treatment for 6 weeks. Evaluation of platelet counts, bleeding scores and safety parameters will be done weekly. All patients are eligible to continue on active, open LGD-4665 treatment for an additional 12 weeks with optimal adjustment of dose for each patient.
The main purpose of this study is to look at the effect (efficacy) and safety of efgartigimod IV in participants with primary immune thrombocytopenia (ITP). After an up to 2 weeks screening period, eligible participants will be randomized in a 2:1 ratio to receive either efgartigimod IV or placebo IV, respectively during the double-blinded treatment period (DBTP). At the end of the treatment period (up to 24 weeks), all participants will receive efgartigimod IV during the first 52-week open-label treatment period (OLTP1). At the end of the first OLTP1, participants may begin a second 52-week OLTP2. After the OLTP2, the participants will enter a follow-up period (approximately 8 weeks) while off study drug. The participants will be in the study for up to 138 weeks.
This is an open-label, multicenter study to evaluate the safety, tolerability, and efficacy of HMPL-523 in adult subjects with ITP.

Evaluate the safety and tolerability of avatrombopag given for 90 days after stopping treatment with eltrombopag or romiplostim.
This is an open-label long-term multicenter phase 3 trial to evaluate the efficacy and safety of ARGX-113 in adult patients with primary ITP.
This is a randomized, double-blind placebo-controlled multicenter phase 3 trial to evaluate the efficacy and safety of ARGX-113 in participants with primary ITP.
This is a 2 part (Part A and B) adaptive, open-label, dose-finding study of PRN1008 in patients with ITP who are refractory or relapsed with no available and approved therapeutic options, with a platelet count \<30,000/μL on two counts no sooner than 7 days apart in the 15 days before treatment begins. The dose-finding portion of the study has been completed. Part B treatment dose is 400 mg twice daily.
Pre-clinical and clinical evaluations show that PRTX- 100 has biological activity that may lead to improved platelet levels where these are decreased due to immunological pathologies and that PRTX-100 has an acceptable safety profile. In vivo treatment with PRTX-100 has been shown to raise platelet counts in a mouse model of immune thrombocytopenia (ITP). The primary objective of the study is to assess the efficacy of PRTX-100 in terms of platelet response in patients with chronic/persistent ITP. Funding Source - FDA OOPD (1R01FD005750-01A1)
The primary objective of this study was to assess the long-term safety of lusutrombopag in the treatment of adults with relapsed persistent or chronic ITP with or without prior splenectomy.
The purpose of this study is to assess the safety and tolerability of BMS-986004 when administered in subjects with ITP.
Core study: To compare the efficacy of avatrombopag (in addition to standard) of care to eltrombopag (in addition to standard of care) for the treatment of adult participants with chronic immune thrombocytopenia (idiopathic thrombocytopenic purpura \[ITP\]) as measured by durable platelet response. Open-label Extension Phase: To evaluate the safety and tolerability of long-term therapy with avatrombopag in participants with chronic ITP (cITP).
Primary Objective: - To evaluate the effect of BIVV020 on the durability of platelet response in participants with persistent/chronic immune thrombocytopenia (ITP) Secondary Objectives: * To assess the safety and tolerability of BIVV020 * To assess the pharmacokinetics of BIVV020 * To assess the response rate of treatment with BIVV020 * To assess the time to response * To assess the effect of treatment with BIVV020 on the requirement for rescue ITP therapy * To assess the immunogenicity of BIVV020
Primary immune thrombocytopenia (ITP) is a rare disease that results in low levels of platelets - the cells that help blood clot. The main aim of the study is to check for side effects from taking TAK-079 at three different dose levels. Another aim is to learn if TAK-079 can increase the platelet count in people with ITP. In addition to receiving stable background therapy for ITP, participants will receive an injection of either TAK-079 or a placebo once a week for 2 months. A placebo looks like TAK-079 but will not have any medicine in it. After treatment, all participants will be followed-up for another 2 months. Then, participants who received TAK-079 will continue to be followed-up for an extra 4 months. Participants who received the placebo and would like to receive TAK-079 may be able to do this in an extension period in the study.
A open-label, multi-center 2-year safety study to ascertain the baseline levels of bone marrow fibers in previously treated adults with chronic immune (idiopathic) thrombocytopenic purpura (ITP) and to evaluate the long-term effect of eltrombopag on bone marrow fibers. The study will also describe the long-term safety and tolerability of oral eltrombopag treatment in subjects with chronic ITP.
This is a randomized, double-blind study of rilzabrutinib in patients with persistent or chronic ITP, with an average platelet count of \<30,000/μL (and no single platelet count \>35,000/μL) on two counts at least 5 days apart in the 14 days before treatment begins. Patients will receive rilzabrutinib or placebo 400mg twice daily. For each patient, the study will last up to 60 weeks from the start of the Screening Period to the End of Study (EOS) visit. This includes Screening (up to 4 weeks) through a 12 to 24-week Blinded Treatment Period followed by a 28-week Open-Label Period. Followed by a 4-week post dose follow-up. For adult participants, the maximum duration of the long-term extension (LTE) period will be 12 months from the date of the last adult participant to enter the LTE. For pediatric participants, the maximum duration of the LTE period will be 12 months from the date of the last pediatric participant to enter the LTE.
